Application filed February 1,1907. Serial No. 355,253.

To all 'whom it may concern:

Be it known that I, .losPH A'. GORDON, a citizen of the United States, residing at Shawnee, in the county of Pottawatolnie and 'lerritory ol Oklahoma, have invented new and useful Improvements in Telephone .l\ttnclnnenls, ol' which the following is a speciiication.

The invention relates to imlirovement in telephone attachments, comprehcnding specifically an auxiliary mouth piece designed lo be applied to the mouth piece ol a transmitter ol' an ordinary telephone for individual use.

lhe main object oi the invention is the provision of an independent mouth-piece constructed ior ready application to and removal from a telephone transmitter to provide l or its individual use by the owner to protect him rom possibility ol diseased communication incis dent to the use oi' the usual mouth-piece.

The prelerred details oi construction will be described in the following specilication, reference being had to the accompanying drawings, in Whiehz- Figure fl is a view in [ront elevation ol' my improved mouth-piece. Fig. 2 is a vertical sectional View, part in elevation, illustrading the application ol' the improvement. Fig. 3 is a rear elevation oi the improved moutlispiece, the relative position o the telephone mouth piece being shown in dotted outline. I

Referring to the drawings my improved mouthpiece comprises a disk l, which may be constructed of any substantial material, and is preferably Yformed with a peripheral [lange 2 to support the transmitter mouth piece engaging means. The disk l is formed with a central opening 3 corresponding in size to the mouth of the usual transmitter, the edge oi said opening being formed with an inturned [lange 4 arranged at an incline to the plane of the disk. The opening ormed by the inner or l'ree edge oi' the flange 4 is bridged or covered by a section ol` screen cloth 5, the marginal edges ol' which are disposed' on the relatively outer surfaces of the flange L1 and secured thereto. The screen cloth 5 may ill desired be impregnated with a suitable antiseptic lotion, though this is not absolutely essential for the purposes of the invention.

At diametrically opposite points the marginal flange 2 ol' the mouth-piece is provided with l'ulcrum pins (i, in each ol which is a pivotally mounted lever 7. The levers are ol` identical construction being in gradual curved l'orin longitudinally, having one end projected through an opening 3 in the flange 2 to provide a push pin 9, the opposite end o' thelever being inturned to provide a bearing or clamping end l0. The free extremity ol the end l() is inclined as at lll to bear throughout its width on the outer surface oi the transmitter tube l2, which is constructed to provide the usual liar-e. Springs 13 are secured to the inner surface oi the marginal flange 2 with their free ends projected to beary upon the lever 7 above the clamping end l0, said levers being preferably provided with retaining pins 14 to prevent accidental disengagement of the springs.

In use the auxiliary mouth-piece is applied directly to the end of the mouth tube of the transmitter-,the push pins 9 being pressed upon to cause a relatively outer movement oi the clamping end l0 of the lever 7. ln this position the flange 4 oi the mouth-piece is' inserted within the tube l2 until the disk l. bears against the iree edge of said tube. Pressure upon the pins 9 is released permitting the springs 13 to orce the clamping ends oi the levers into coperative engagement with the relatively outer surface oi the tube l2, thereby securing the mouth-piece in applied position convenient ior use.

The object o this invention is to provide an auxiliary mouth-piece designed 'lor ready application to the mouth tube oi a telephone transmitter, the mouthpiece being readily removable to' provide lor the owner applying the individual mouth-piece when he desires to use the telephone. As the structure described provides a device which may be readily carried by the user it is obvious that l thereby enable each individual user ol' a telephone to carry and make use oi his own mouth-piece when using a telephone, thereby reducing to a minimum if not actually preventing that possibility of diseased contamination ordinarily incident to the general use of a telephone transmitter by a number of persons.

While preferring the parts to be constructed of metal, it is obvious that the use of any material having suflicient rigidity to support the parts described would be serviceable, and I therefore contemplate the use of any material andthe particular arrangement oi' the coperating parts of the mouth-piece to conform to any oi the Kaccepted types of telephone transmitters to be used` Having thus described my invention, what l claim as new is- 1..An auxiliary mouth-piece for telephones comprisinga disk formed with a central opening .and with a marginal flange, an inclined flange projectingl from the disk in alinement with the wall of the opening'. a screen covering for the inner edge of said inclined flange, and locking levers carried by the marginal angc.

2. An auxiliary mouth-piece for telephones comprising ya disk formed with a central opening and with a marginal' flange, an inclined flange projecting from the disk in alinement with the wall of the opening, a screen covering for the inner edge of said inclined flange, and locking,r levers carried by the marginal flange, said levers being formed with inclined clamping ends, and being terminally projected beyond the marginal fiange fo provide push pins. In testimony whereof, I affix my signature in presence of two witnesses.
